Abstract
A two-dimensional (2-D) inclinometer based on three optical fiber Bragg gratings (FBGs) is proposed and demonstrated. Preliminary experiments show that a high measurement sensitivity of 192 pm/° and resolution of 0.005° can be achieved and this sensor is proved to be insensitive to temperature.
